Bluetooth Headphones & Earbuds: My Recommendation After Trying 7 Pairs

I started this post several months ago, and hadn't finished it.  With announcement of of Apple's new Airpods, I'm getting asked more about wireless headphones, and this will serve to summarize my experiences and recommendations. I hope it helps you!

Wireless Headphones are Great

The first question is of course "Why?"  Why bother with wireless headphones when there are plenty of serviceable, inexpensive wired ones?

I was surprised just how freeing going wireless was, and for me - it's worth the added hassle of having to keep them charged.    It feels significantly faster and more convenient because:

  •  fewer wires to untangle when I get them out
  •  no wire to snake through my clothing and have in my pocket
  •  nothing poking out of the bottom of my phone making it larger in pockets
  •  nothing to unplug or get tangled when removing my phone from my pocket

My Two Favourite Types

I find these two types very useful:

  • over the head "studio style" headphones
  • two-earbuds-on-a-wire style earbuds.

The headphones style are great for throwing on quickly, and their size means battery life is great - 5 hours to 30 hours of playback on pairs I've tried.    Controls on the ear piece, which is large enough to operate easily.

I find the two earbuds style vastly superior to the single earbud "cyborg-style" that have been popular with real-estate agents and the upwardly mobile for making calls for years.      The two earbuds hangs easily around my neck, so I can use them and remove them without having to stuff them in a pocket.  This means I always have them with me - my first wearable device.

Things to look for:
  • Full iPhone support - I've found battery status is not always supported, and it's a great feature to have.  To be able to just look at your phone and know how charged your earbuds are.
  • Standardized forward & back controls.
  • Standardized call button controls to trigger Siri.


As anyone who follows tech closely will tell you - Bluetooth isn't the greatest of wireless technologies.  Even the Apple watch and iPhone have connection glitches, and they're made by the same company.  I'm hoping Airpods will improve on this, but we'll see.  ( I also think I will prefer the 2-earbuds-on-a-wire style, but again - we'll see when they come out...)


The ones I recommend are the Jaybird X2. Although they are pricey (about $200 Canadian), the 8 hour battery life is unmatched, the sound quality is good for music as well as talking & podcasts, and the controls are consistent and well built.   Other cheaper versions I tested (about 5 pairs!) were just not as good on all these dimensions.

Update, 24-Aug-2017:

Jaybird X3:  I have also now tried the Jaybird X3, and immediately returned them.  The have a proprietary connector that attaches to the microphone & volume adjustment.  If you lose the adaptor or are not where you have the adaptor, you can't charge them.  This was a show-stopper for me.
They also made the microphone & volume buttons larger and heavier - which seemed significantly inferior to me.

Apple Airpods:  I have also got a pair of the Apple Airpods now too.   I've had them for about 6 months, and the are very good.  The easy use & switching between mac, iPhone, and iPad due to their "W1 Chip" is a huge win, and while I can quibble about how well it works a bit, it's really great.

The lack of wire to connect the two is an issue for me, as described above.  It's a win for simplicity, and makes the case possible, which is also a hugely important win/part of the product.
That said, the lack of joining-wre also takes away from the jobs it does for me.      One key place is on my bike.  I find that my helmet straps knocks them out of my ears, and they fall off - a show stopper for biking, so I don't use them for that case.

I also choose the Jaybird X2 for my every day use at work, due the joining-wire that means I can more quickly pop them out of my ears, let them dangle, and then tuck them into my shirt.

I know, I know - first-world problems - but these are the details of my everyday experience with the various types.  Thanks for reading & my best to you!

My Achalasia Story

Manometry charts showing Achalasia subtypes
Achalasia is a disease of the esophagus, which attaches between your voicebox and your stomach.   Normally food is pushed through the esophagus with involuntary muscle contractions called peristalsis.   In rare cases, this behaviour fails for unknown reasons.  The result is difficulty swallowing food, and eventually liquids.  Patients with Achalasia usually experience significant weight loss, a lot of discomfort while trying to swallow, and must adapt their diet to softer and softer foods like soup and mashed potatoes.

I started experiencing Achalasia symptoms in May or June of 2015.  They progressively got worse, to the point that I couldn't drink fluids in March of 2016.   I had lost 25lbs, and had become dehydrated and malnourished by the time I was admitted to hospital for surgery that would mitigate the problem.

What I hope to Achieve with this Post

  1. Summarize what happened for interested friends and family
  2. Help increase awareness about this disease, as it is frequently mis-diagnosed 
  3. Hopefully help others with Achalasia by sharing how my story unfolded


Achalasia has an incidence of about 1 per 100,000 per year, and a prevalence (how many people are living with it) of about 1 in 10,000.

Mine started in June of 2015 with the experience of being at a conference dinner table, and not being able to get food to go down properly.   This discomfort persisted for a couple weeks and I went to see my family doctor about it.      I had been experiencing pretty severe heartburn for about 6 months prior to this, or certainly chest pain that I interpreted as heartburn.

I was sent for a couple of tests over the summer - a Barium Swallow/Xray which showed "esophageal spasms" and not much reflux from my stomach.   The next test was to send a Endoscope (camera) down my throat, for which I was mercifully sedated, and it showed nothing out of the ordinary.     I was seeing a Gastroenterologist by this point and he was convinced it was acid reflux - often clinically called GERD.    We managed to get these tests done relatively quickly by being available at short-notice for cancellations.

My wife and I were of course doing our own research, as it was persistently uncomfortable, and I had been limiting my diet to try to get relief from the reflux and discomfort.  Achalasia is rare enough that  it is often misdiagnosed as GERD, and this happened in my case as well.   Thanks to the help of this great blog by an engineer in Ontario, my wife identified correctly that my symptoms sounded a lot more like Achalasia than GERD.

This was in August.  The most frustrating part of this whole experience was the waiting for further tests, appointments and stages.  For example - we were sure it was Achalasia in August, and it took until the end of February for my turn to get the definitive test that would confirm Achalasia: esophageal Manometry (examples of the results pictured above).   During that time I had gone from discomfort - eating softer foods over the course of an hour  - to being reduced to 3 to 4 boost-type drinks per day with hopefully some soup and/or well-mashed potatoes with gravy.


At the end of February, the Manometry test confirmed what Lauren and I were already certain of:  Achalasia.  Fortunately we had done our advanced reading and so were aware of the options and ready to go to the current best practice treatment which is a Heller Myotomy, with a Dor Fundoplication.

Unfortunately, there was more waiting (and corresponding suffering for myself, my wife, and my extended family) in the non-urgent stream of the Canadian medical system.   I'm a fan of our system in general, but waiting at sometimes becomes unbearable.  By this point many in my family were getting quite worried, as I was now down 25lbs, and at times unable to eat even soup.


My surgery consult took a couple of weeks to be scheduled,  this initial appointment to discuss options with the surgeon was 5 weeks after the manometry test, with the prospect of having the surgery 5 to 8 weeks after that.  Unfortunately my ability to take in fluids and nutrients had continued to deteriorate, to the point that I went to emergency in later March, as I was unable to take in fluids and had become both dehydrated and deficient in nutrition (as well as sleep).

I was not sleeping several nights a week because food that had not gone down would come up in the middle of the night, waking me up to choking on it every 20 minutes or so.

I was admitted as an emergency patient because I was no longer able to get enough nourishment down, and put on an internal hospital waitlist for the surgery.  After another 5 days of eating & drinking absolutely nothing except for IV fluids,  I had the surgery in time for Easter.

Current Situation

I'm currently 2 weeks post operation, and already feel significant improvement.  I'm able to eat soft foods, including one of my favourites - Shepherd's Pie - as long as the quantities are kept small.   I look forward to returning to a mostly normal diet.
